CORN-PLANTER `CHl'iCK-ROWER.

j .SPECIPICATICN forming part of Letters Patent No. 303,169, datedAugust 5, 1884.

Application filed January l2, 1683. (No model.) l

To all whom t may concern:

Be it known that I, JAMES C. LEIDY, a citinen ofthe United States,residing at Galesburg, in the county of Knorr and State' of Illinois,have invented certain new and useful Improvements in. Gern-PlanterCheclrItowe1s; and I de hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference .marked thereon, which forni a part of thisspecification.

This invention relates to corn-planter checkrowers of that class inwhich the check-row devices are actuated by knots or ta-ppets on astretched wire; and the invention consists in constructions andcombinations hereinafter described, and set forth in the claims heretoaunexed.

In the accompanying drawings, which illustrate my invention, Figure l isa top plan. Fig. 2 is an end elevation. Fig. 3 is a plan of one end ofthe device seen from below. Fig. is a front side elevation. Fig. 5 is aperspcctiveof the central part of the planter slidebar and connectionsof the check-row devices thereto. Fig. 6 is aside elevation of twosections of the clieelorow chain or tappeti-wire.

Fig. 7 is a sectional. plan of the wheel which .ierent figures, Arepresents the ordinaryhar,

to each end of which similar devices are attached, as shown at Fig. l,but only one of which need be described herein.

B is a T-shaped head, fixed to the end of bar A, and provided withordinary guidepulleys, D D', for the ordinary tappet-wire, C.

D is a heiter-wheel journaled to the outer end of the head B, and ingear with a smaller imiter-wheel, D", which is journaled to the upperside of head B. Ordinary forked arms, E, are radially adjustable on thewheel D, and are held after adjustment by bolts e, which pass throughslots in the arms E and into the wheel D. By adjusting the arms E, theproper length of time of Contact of the tappcts o on the wire C with theforked arms E maybe regulated, and by said arms being bolted to wheel D,if either gets broken, it may be replaced by a new arm.

F is a frame, with arms f, which are hinged to the bar A, and an arm,f', to which a friction-wheel, G, is journaied, and a rear projectingarm, f, with a spring, f, between it and the bar A, which spring tendsto hold the rim of the wheel G in frictional contact with the side ofthe wheel D. The side oi' the wheel D next the wheel G has depressionsg, one between each pair of arms. E, or in such positions that afteratappet on the cheek-row wire has acted on one of the forked arms E thewheel G will be pressed by the springf into one of the depressions qwith sufficient force to hold the wheel G and other parts of 7o thedevice, and thereby prevent accidental movement of the planterseedslides from jarring or tilting of the planter, and also hold thewheel D in such position that one of its forked arms E will always be inproper position for the action of a tappet c. W'hen a tappct c acts onthe wheel D, the spring f will yield, and allow the wheel G to yieldbaekwardto permit movement ofthe wheel D.

II is a lever, pivoted, as shown, tothe bar A.

I is a connecting-rod. The miter-wheel D has av crank-pin, (Z, on whicha sleeve, d', is eccentrically journalcd, and held, after radial adjustnicnt, by a nut, d", on the outer end of the crank-pin. Theeonnectingrod I is hinged to the upper end of' the lever I-I, and may beturned over to engage a strapy, on its free end with the eccentric onthe wheel D at either side of the machine, as shown by full and dottedlines at Fig. l.

J is an arm, which may be adjusted higher and lower in a slot, 7L, inthe lower end of the lever H, and held after adjustment by a nut, ii.

J is a sleeve cccentrically journaled on the arm J, so that it may beadjusted radially on the arm J, and held after adjustment by a nut, j,on said arm J.

K is the central part of the ordinary connecting-bar between thesecdslides of the planter.

IOO

L is a plate, with a vertical slot, Z, in each 1 end, through whichbolts l pass to secure it to the Abar K, as shown. adjusted vertically,and held after adjustment by the bolts Z.' Arms L project upwardly fromthe plate L, between which arms L the eccentric J operates. By adjustingthe sleeve J radially on the arm J the device may be made to give a veryexact throw to the seedslides in either direction, and by adjusting thearmv J vertically on the lever H the extent of throw of the slides maybe regulated as desired. rIhe extent of throw of the seedslides may bemore finely adj usted by 4adjusting the eccentric d on the crank-pin d.The arm J is long, so that it may seat properly in the arms L inplanters of different construction.

The operations of the device further than hereinbefore described will beevident to any one skilled in the art. In passing in one directionacross the field the connecting-rod I is connected with the miter-wheelD at one side of the machine, and in passing across in the oppositedirection it is connected with the ruiter-wheel at the other side of themachine, whereby the devices at one end of the bar A remain stationarywhile those at its other end are in operation. Each tappet, in operatingon a forked arm, E, brings another forked arm into proper position forthe action of the next tappet. My tappet-wire, with tappets or knots c,is formed as shown at Fig. 6. The sections c of the wire are united bythe tappet c, which is a link with an enlarged end, c, through which theend of one section of wire passes, and has a head, c", formed thereon,which holds the wire therein and forms a swivel. VThe end of the othersection of wire is passed through the other end of the link or tappet c,and bent back upon itself, and secured by ceiling the end upon the mainportion, as shown at same figure. I thus unite the sections of wire andthe tappet, so as to form a universal-joint connection between thesections of wire, and also a swivel, to permit iexure in any directionbetween the sections of wire, and to relieve the wire from any torsionalstrain.

What I claim as new, and desire to secure by Letters Patent, is-

l. In combination with the tappet-wire and The plate L may be l themiter-wheel D, having radial forked arms E attached to its disk, -themiter-wheel D', connecting-rod I, and lever I-I, connected with theseed-slide-operating bar, substantially as and for the purposespecified.

2. In a check-rower, in combination with the ruiter-wheel D, havingforked arms E attached to its disk, lever II, connected with theseed-slide bar, connecting-rod I, having strap t' on its end, thevimiter-wheel D, having -a crank-arm, with an eccentric sleeve journaledthereon, substantially asfand for the purpose specied.

3. In combination with wheel D, having forked arms, wheel D', havingcrank-arm, and lever H, for operating the seed-slides, theconnecting-rody I, hinged to lever H, and adapted to engage with 'wheelD on either side of the planter, substantially as and for the purposespecified.

4. In a check-rower, in combination with the seed-slide bar,connecting-rod I, adapted to be operated by suitable mechanism connectedwit-h a tappet-wire, and lever II, the arm J, having sleeve Jeccentrically journaled thereon, substantially as and for the purposespecified.

5. In a check-rower, in comblnation with a tappet-wire and a wheelD,having forked arms E, the yielding friction-wheel G, adapted to act indepressions in one side of wheel D, substantially as and for the purposespeciiied.

6. In combination with forked lever-carrying wheel D, with depressions gin one side, the yielding friction-wheel G, adapted to enter saiddepressions, substantially as and for the purpose speciied.

7. A check-row tappet-wire formed of scctions c', one of which isprovided with au eye formed by coiling its end upon itself, and theother provided with a head and an interposed link joined to sections,substantially in the manner shown.

In testimony whereof I affix my si gnature in presence of two witnesses.
